1. To find the sales tax rate you can set up the equation:
1200x = 72; divide both sides by 1200
x = 0.06
The tax rate is 6%.
2. 6% of 2500
0.06 x 2500 = $150
For Part A, the answer is d.
3. 6% of x is $108
0.06x = 108; divide both sides by 0.06
x = 1800
The answer for Part B is letter d.

Answer: 8mn5 – 2m6 + 5m2n4 – m3n3 + n6 – 4m6 + 9m2n4 – mn5 – 4m3n3
Answer:
x=½
y=5
Step-by-step explanation:
(8x+7y=39)2
16x+14y=78
<u>4</u><u>x</u><u>-</u><u>1</u><u>4</u><u>y</u><u>=</u><u>-</u><u>6</u><u>8</u> add the two equations
20x=10.
divide both sides by 20
x=½
8x+7y=39
4+7y=39
7y=39-4
7y=35
y=5
